Purple Loosestrife: An Attractive but Deadly Threat to California Wetlands and Waterways

Why be concerned about Purple Loosestrife?

• Purple loosestrife has taken over waterways across the United States, invading wet areas such as lakeshores, stream banks, marhes, ditches, and canals.
• Purple loosestrife spreads uncontrolled in North America because it escaped its specialized insects and diseases that kept it in check in its native lands.
• One plant can produce up to 2.7 million seeds, allowing the plant to spread quickly.

Purple Loosestrife forms solid stands that:

• Displace native vegetation and associated wildlife
• Decrease water flow and quality
• Disrupt irrigatin systems
• Diminish recreation
